RE: RegExp issues with Tomcat 5
On a side note, try using bind variables (prepared statements) in your sql statements. This way, you don't have to escape anything, gain performance and avoid sql-injection attacks.

Re: RegExp issues with Tomcat 5
Karl,
Using the regexp tag library I think it is still at version 1.0.
Because INSERT into tablename (field1) values ('I CAN'T DO THIS')
generates an error in SQL Server.
If you use a PreparedStatement, then you can send any string to the
statement object and it will do it's own escaping.

RE: RegExp issues with Tomcat 5
Hi, We upgraded tomcat running one of our applications from 4 to 5 this past = Friday, March 27th. Since, one of our regular expressions is not = functioning properly. Here is the expression: s/(\\|')/\\$1/g Instead of escaping the apostrophe with another apostrophe for SQL = purposes, it is replacing the apostrophe with the literal '$1'. It was = working with Tomcat 4 and that is the only thing that has changed. So. What are you suggesting? ;) The jakarta-regexp that tomcat uses to handle regular expressions has not changed since September 2003, so many of the tomcat 4.1.x releases have used it. Did you use these tomcat 4 releases without a problem? Alternatively, if you're referring to regexps directly used in your application, and you're using JDK regexps (the java.util.regex package), obviously tomcat has nothing to do with that. Is the rest of your webapp functioning properly in tomcat5, or are there other errors that perhaps make this regexp one come up?

RE: RegExp issues with Tomcat 5
We are using the regexp tag library in our jsp's. Yes, it worked fine with Tomcat 4. The rest of the application is working fine. Users just started noticing that where they are putting apostrophes and saving, when they bring the information back up it shows as $1. Mary's purse is being brought into the application as Mary$1s purse. It is like it isn't interpreting the meaning of the $1 anymore.

Hi, Using the regexp tag library I think it is still at version 1.0. You mean http://jakarta.apache.org/taglibs/doc/regexp-doc/intro.html? I wouldn't be surprised if this taglib didn't work on tomcat 5. It's designed and tested for a JSP 1.1/1.2 spec container, like tomcat 4. Tomcat 5 as you know implements the JSP 2.0 spec, with its new expression language and several changes to expression evaluation. It'd be almost shocking if the taglib worked without modification on tomcat 5. Ask on taglibs-user (http://jakarta.apache.org/taglibs/index.html#MailingLists).
