Getting around JSON response error

[Sean Adams-Hiett]

Great work on this project! Very cool concept and execution.

I have been trying to follow the demo, which I am hoping to adapt for a project that I am working on.  I am running into issues with the "Talking to Solr" step, which appear to relate to the json (jsonp?) response. When I change out provided solr url with the url to my solr instance, I am getting the follow error when the page is loading:

Uncaught SyntaxError: Unexpected token ILLEGAL (chrome)

unterminated string literal (firefox)

I gather from reading up on this that this has something to do with the way the json is formatted and problems with U-2028 and U-2029. I have read the following threads to see if there are any workarounds:

• https://groups.google.com/d/topic/ajax-solr/Twmh0HNPmVA/discussion
  
• https://groups.google.com/d/topic/ajax-solr/ON5Lu1Tg5dc/discussion
  
• https://groups.google.com/d/topic/ajax-solr/5pBxSFVrulk/discussion
  

I'm not finding anything that seems like someone has figured out a solution yet.

I am using Solr 3.5 running as a Tomcat6 webapp on a hard drive.

Is it possible that there is an issue with my solrconfig.xml?

[James McKinney]

See this Solr issue: https://issues.apache.org/jira/browse/SOLR-2520?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel It was apparently fixed in Solr 3.2.

What happens when you run the Solr response through http://www.jslint.com/? or if you try to evaluate it with JSON.parse? can you evaluate it with eval()?

What version of jQuery are you using? In Manager.jquery.js, have you tried removing "json.wrf=?"?

[Sean Adams-Hiett]

Removing the "json.wrf=?" caused those errors to go away. Now I seem to have stumbled onto a more fundamental issue. The Manager.afterRequest() is never firing.  I went and took a look at the json that was coming back and I noticed that it seems to have no closing brackets.  Here is an example:

we would ordinarily not consider ourselves in favor of consolidation for this district, we are strongly in favor of it in this particular situation it is possible for other districts to take territory from this district until we havo only sixteen sections remaining; in order to maintain the school at its pri-sent standard it would then be necessary to raise the tax rate from the present thirty-two mills to something over forty mills. we have no new building to erect, most of our equipment in here, consolidation would reduce the expense of operation by reason of the closing of tho outside schools, an additional $500 in state aid would be secured for next year; prnctirally no change (as explained last week) need be made in the school itself, we would have a larger terrl-tnr\\ from which to draw the running expenses - ' can see no reason why the tax rate should be raised at all next year under consolidation.an informal vote will be taken on tho day ot tho election to decide as to

plowed it under, we were doing a good job. but now we know that won't do. to do any real good, the manure must be broken up into small pieces and spread evenly.the low cloverleaf spreader is the one that does this \\vork best. it gives the manure two healthy beatings, one with the regular beater, the other with the wide spread disks. when the manure reaches the ground in that condition your soil

So, that clearly seems to be a problem. To test this out, I went into the Solr Admin and did a "*:*" search from there, and then manually added the "&wt=json" to it. I spot checked half a dozen records by changing the "start=" and every one I looked at seems to suffer from this same issue.

I know this is outside the scope of Ajax Solr, but do you have any idea why that could happen?

[Sean Adams-Hiett]

I should probably also add that when I looked at the same results using xml, I didn't see any problems.

[James McKinney]

It may be a Tomcat issue. People had a similar issue when using Jetty, and switching to LucidWords fixed it. I recommend sending your question to the solr-user mailing list: http://lucene.apache.org/solr/mailing_lists.html
